What is recorded here

Man-made underground passage in Glen (leyny By.) is a man-made underground passage in Glen (leyny By.), County Sligo, Ireland. It appeared during 2001 land reclamation works on a south-east facing slope in rough hilly pasture. The circular chamber has a base diameter of about 2 metres and surviving wall height of about 1.2 metres. A narrow passage extends north-northeast from the chamber, though soil blocking prevented full inspection.

In pasture, located on a SE-facing slope in rough hilly terrain. This Man-made underground passage was exposed in 2001 during land reclamation works. Inspected in October of that year, it consisted of a circular drystone chamber (diam. at base c. 2m) of corbelled construction. The upper quarter of the chamber was destroyed but the walls of the lower part of the chamber remained intact to a height of c. 1.2m. A passage (Wth c. 0.95m), with drystone walls constructed of relatively small stones, roofed with large, flat slabs, extended to NNE from the NNE end of the chamber. The passage was partly infilled with soil and could not be investigated. Compiled by: Jane O'Shaughnessy Date of upload: 23 July 2015
